SMOKING-PIPE SHIELD.

Application filed November 30, 1910, Serial No. 594,884.

the wind from blowing out the lighted to,

bacco or preventing the rain from entering the bowl and extinguishingthe light.

The invention has for one of its objects to provide an extremely simple,practical and effective shield which can-be readily applied to orremoved from the bowl of the pipe, and which when in position preventswind or rain from putting out the lighted tobacco, although ampleprovision is made for allowing an effective draft through the lVith suchobjects in view and others, as will appear as the description proceeds,the invention comprises the various novel features of construction andarrangement of parts which will be more fully described hereinafter andset forth with particularity in the claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention, Figure 1 is a perspective view of a shield in appliedposition and partly broken away. Fig. 2 is a central vertical section.Fig. 3 is a bottom plan view. Fig. 4 is a perspective view of thevarious part-s of the shield before being riveted together.

Similar reference characters are employed to designate correspondingparts throughout the views.

Referring to the drawing, the shield will be observed to be composed ofthree essen tial parts, namely, the cap piece A, the bottom piece B, andan attaching device C. The cap piece is a metal or other disk which hasits peripheral edge curved downwardly so as to provide a cap hollow atits under side. This cap has a central opening 1 through which passes arivet 2 that secures the several parts together. The bottom plate B isin the form of a disk of the same diameter as the cap and the majorportion of this plate is bowed upwardly or arched.

into a crown or dome 3, so that the cap 1 will rest 'directly thereon.The annular flange 4 of this bottom plate is spaced from thedownwardly-bent edge 5 of the cap so that a continuous annular openingor entrance 6 is provided around the periphery of the cap. Arrangedaround the dome 3 and adjacent the flange 4 are openings or apertures 7that form communicating means between the annular entrance and thechamber formed by the dome, said chamber being in open communicationwith the bowl of the pipe D. By this arrangement, air is drawn laterallythrough the shield and then downwardly into the pipe bowl. Since the capis rounded at its edge, rain will be readily shed thereby and preventedfrom entering the shield. Furthermore, by the re stricted entrance 6extending around the periphery of the shield,it is impossible for windto pass into the pipe.

The attaching device G consists of disk 8- of such diameter that it canbe placed in the hollow of the bottom plate 2 without obstructing thepassage of air through the apertures 7, and on this disk, which is fastened in place by the rivet 2 passing through it and through the bottomplate, are spring lugs or attaching members 9 which extend into the bowlof the pipe and frictionally engage with the internal surface thereof,the flange 4 of the bottom plate resting on the top of the bowl. Byattaching the shield in this manner, it can be effectively held in placeagainst accidental dislodgment and at the same time it can be readilyremoved when it is necessary to clean out and re-fill the pipe.

Having thus described the invention, what I claim as new, is

1. A pipe shield comprising a cap piece, a bottom piece having a centralcrown extend ing into the cap and provided with apertures extendingaround the crown, an at taching device disposed under the bottom piecefor engaging the bowl of a pipe, and means for fastening the said partsto gether, said bottom piece having its peripheral portion spaced fromthe cap to provide an annular entrance for air.

2. A tobacco pipe shield comprising a cap piece, a bottom piece ofsubstantially the same diameter as the cap piece and formed with aperipheral flange spaced from the cap means and through the cap andbot-tom piece to provide an annular entrance and pieces for securing theparts together. 10 also formed with a central crown on which Intestimony whereof I aflix my signature the cap bears, said crown havingapertures in presence of two witnesses.
